一般說明

元素硫存在于30种不同的固体同素异形体中，其中斜方硫是常温常压下唯一的热力学稳定形式。它可溶于许多有机溶剂，生成大量含氧酸。硫的反应性通常很高；元素硫的S8环很容易被许多亲核反应物破坏。大约在100oC下，羟基离子可与S反应。

應用

它可用于Li-S聚合物电池，也可用作太阳能电池的半导体敏化层CdS/CdSe/ZnS。

Low-dimensional materials usually exhibit mechanical properties from those of their bulk counterparts. Here, we show in two-dimensional (2D) rhenium disulfide (ReS2) that the fracture processes are dominated by a variety of previously unidentified phenomena, which are not present in bulk

The newly prepared complex [Pd(IPr*(OMe))(cin)(Cl)] provides high catalytic activity for carbon-sulfur cross-coupling reactions. Nonactivated and deactivated aryl halides were successfully coupled with a large variety of aryl- and alkylthiols using this well-defined palladium N-heterocyclic carbene (NHC) complex.
